-Be aware, that the template file [plotly.tmpl](generator%2Ftemplates%2Fplotly.tmpl) also has a go generate directive.
-This directive has relative paths, based on the assumed final path within the project

-#### embedding a downloaded plotly js source
-
-In the example: [main.go](examples%2Fbar%2Fmain.go) you find an example to reuse a static plotly js file and pass that reference to the generated html, instead of using a hardcoded CDN reference which would require internet connection.

-## Update Notes:
-
-### Add version v2.29.1 and v2.31.1
-- Added Downloader for schema file
-- added generator for different packages based on plotly version in subfolders for each version
-- enable easier use for different plotly version by new import paths which include the version generated. Example: `grob "github.com/MetalBlueberry/go-plotly/generated/v2.31.1/graph_objects"`
-- removed go generate directive from the templates which are no longer necessary
-- removed offline package, as each version package needs its own **plot.go**.
-- Replaced all `offline` imports in the examples packages by just calling the `grob` package of the specified version
-- all html's will now refer to the correct plotly version's cdn in the html's head
-- allow defining your own head for the plot, which allows embedding the plotly.js source instead of referencing the CDN. This enables generation of offline plots
